Access to *one* Steam folder from WinXP and Win7

[z0ttel]

Hello everybody,

yesterday I've set up Windows 7 on my PC beside the existing Windows XP (on a separate partition, of course).
Now my question is if I can use the Steam folder which has been set up and used from WinXP till now directly from Win7, too or if I have to install all the games a second time only for Win7?

I tried to start the steam.exe of the existing installation and it seemed to work - even COD ran fine, but I'm a little bit curious if this is ok (you know, no registry entries in Win7, ...)?
